2 Press to display the setting
screen shown to the left.
:
The screen varies depending on whether the wiring mode is
1P2W×2 or a mode other than 1P2W.
:
The screen varies depending on whether the wiring mode is
1P2W×3, 1P3W&1P2W and 3P3W&1P2W, 3P3W2M, or 3V3A
and 3P3W3M and 3P4W.
3 Press or to select the channel
to set.
Areas b, c, and d on the display correspond to CH1, CH2,
and CH3, respectively. The selected channel parameter will
flash.
4 Press or to set the zero-
cross filter (100 Hz/ 500 Hz/ 5 kHz/
200 kHz).
Settings: 500Hz→200kHz→100Hz→5kHz ⋅⋅⋅
5 Set the zero-cross filter for other chan-
nels as necessary.
• When using a wiring mode other than 1P2W, the frequency range will be standardized using the CH1 set-
tings.
• When measuring an AC signal with a frequency lower than 500 Hz, it is recommended to set the fre-
quency measurement range (zero-crossing filter) to 100 Hz or 500 Hz to reduce the noise component at
500 Hz and higher. Select the frequency measurement range depending on frequencies of signals to be
measured.
• Frequency measurement accuracy is guaranteed for sine wave input that is at least 20% of the frequency
measurement source’s measurement range. The instrument may not be able to perform frequency mea-
surement accurately for other inputs (when the measurement signal is distorted, when there is a super-
posed noise component, etc.).
• The frequency measurement range cannot be changed while integration is being performed or during dis-
play hold or maximum value/minimum value hold operation.
• If a frequency of a signal to be measured is above the selected frequency measurement range, the instru-
ment may not be able to perform frequency measurement accurately. Change the frequency measure-
ment range to an appropriate one.
(Example) If a signal with a frequency above 500 Hz is input into the instrument with the frequency mea-
surement range that is set to 500 Hz, change the range to 5 kHz or higher.
6 Press to exit the settings.
The instrument will revert to the normal measure-
ment state.
